This Mazda RX-7 FD3S is owned and driven by Takahashi Keisuke, the younger brother of the infamous street racer Takahashi Ryosuke. Keisuke looks up to his brother as an idol and wants to follow in his footsteps. Ryosuke sees potential in Keisuke's driving capabilities and therefore creates a street racing team called the Akagi Red Suns together with him. They were undefeated until Takumi Fujiwara, the Ghost of Akina, beat both brothers in a duel down their home course.
